The divers evolution equipped

From Southeast Asia·An enduring case

The Bajau of Southeast Asia free-dive to remarkable depths, and genetic studies found enlarged spleens consistent with selection for diving over generations. Their knowledge of the sea is simultaneously technique, tradition and physiology. Some knowing is carried in ways no library can hold.

The concepts this raises

Each of these gives a class a different way into the same case.

EvidenceGrounds of Knowledge
What is offered in support of a claim. Evidence is not the same as proof: it raises or lowers how likely a claim is, and its force depends on how it was gathered, what it was gathered for, and what else it is consistent with. Asking what would count as evidence against a claim is usually more revealing than listing evidence for it.
CultureThe Knower's Lens
The shared practices, language and inherited assumptions of a community of knowers. Culture supplies the questions that seem worth asking and the answers that seem obvious, so its influence is hardest to see from inside it.

Where it sits in the knowledge framework

Scope
What this area of knowledge is about, what problems it takes as its own, and where its questions stop being answerable by its methods. Scope is where you examine why a discipline exists at all and what it deliberately leaves to others.

Areas of knowledge

Themes

The same ideas, somewhere else

Cases that raise a concept this one raises, but in a different area of knowledge or a different part of the world. That contrast is the point: it is what shows a student the concept travels.
